What You Need to Make this Healthy Oat Bar Recipe

If you ask me, the best kind of recipes are the ones that feel effortless but taste like you spent hours in the kitchen—just like these oatmeal bars! Simple ingredients, easy steps, and a flavor that keeps you coming back for more. Let’s get started!

For the Oat Crumble Base & Topping:

• 2 cups (225 grams) of rolled oats or quick oats (rolled oats for chewiness, quick oats for softness)
• 1 ¾ cups (210 grams) all-purpose flour
• ¾ cup (165 grams) packed brown sugar
• ½ teaspoon (1 gram) cinnamon
• ½ teaspoon (2 grams) baking soda
• ½ teaspoon (3 grams) sea salt
• 1 cup (225 grams) unsalted butter, melted

You know, I switched to sprouted rolled oats like the one below in my oat bars and it’s been a game-changer—they’re gluten-free, easier on the stomach, boost nutrient absorption by reducing anti-nutrients, and add a naturally nutty flavor that really elevates the taste!

For the Jammy Filling:

• ¾ cup (240 grams) blueberry jam (or your favorite flavor)
• 1 cup (150 grams) fresh blueberries (frozen work too—no need to thaw!)

Quick Note – Not a blueberry fan? No problem! Use raspberry, strawberry, or your favorite jam instead.

How to Make These Chewy Oat Bars

Let’s make these oat bars together—follow these steps and you’ll have a snack that’s perfect for breakfast, lunch, or whenever you’re craving something filling, delicious and homemade.

Step 1: Mix Up the Oat Crumble
Alright, let’s start with the base! Grab a big mixing bowl and toss in your oats and flour. This is what gives our bars that perfect chewy texture. If you’re a fan of a softer bite, go with quick oats. Want a little more texture? Rolled oats are the way to go!

Top Tip: If you want to make oatmeal bars even healthier, you can swap half the flour for almond flour or use coconut sugar instead of brown sugar!

Step 2: Add a Little Sweetness & Spice
Now, let’s sweeten things up. Stir in the brown sugar—it’s what makes these bars chewy and just the right amount of sweet. Then, add cinnamon for that cozy warmth, baking soda for a bit of lift, and sea salt to bring out all the flavors.

Step 3: Bring It All Together
Give everything a good mix so the ingredients are evenly combined. Now, melt some butter (the secret to that rich, buttery crumble!) and pour it over the dry mix. Stir until you get a crumbly, slightly sticky texture. It should hold together when you press it between your fingers—kind of like damp sand at the beach!

Top Tip: If you want to make them dairy-free, just swap the butter for melted coconut oil or a vegan butter substitute!

Step 4: Build the Base
Scoop out a cup of this oat mixture and set it aside—we’ll use it for the topping later. Now, press the rest into a parchment-lined baking pan. Use the back of a spoon (or your hands—no judgment!) to really pack it down. This is what holds everything together, so don’t skip this step!

Step 5: Pre-Bake for the Perfect Texture
Pop the base into a preheated oven at 350°F (175°C) and bake for 10 minutes. This helps it set so the jam doesn’t sink in too much. Plus, it makes the crust slightly crisp on the bottom—so good!

Step 6: Spread the Jammy Goodness
Once the base is out of the oven, it’s time for the best part—the jam! While the crust is still warm, spread a generous layer of blueberry jam all over. The warmth helps the jam melt into the oats, making every bite extra delicious.

Step 7: Add the Blueberries
Now, sprinkle fresh blueberries evenly on top. If you’re using frozen ones, don’t even worry about thawing them—just toss them straight on! Make sure they’re spread out so you get some in every bite.

Step 8: The Final Crumbly Touch
Remember that oat mixture we saved earlier? Sprinkle it evenly over the jam and blueberries. Make sure you cover everything so you get that crunchy, golden topping in every bite.

Step 9: Bake Until Golden & Irresistible
Back into the oven they go! Bake for about 55 minutes, or until the top turns a beautiful golden brown and your kitchen smells like heaven. Seriously, the hardest part of this recipe is waiting for them to finish baking!

Step 10: Cool, Slice & Enjoy!
Now, here’s where patience comes in. Let the bars cool a bit before slicing—this helps them hold their shape. (But hey, if you sneak a warm bite, I won’t tell!) Cut into squares, grab a piece, and enjoy every jam-filled, crumbly, buttery bite.

Can You Make These Oatmeal Bars Gluten-Free? Absolutely!

If you need a gluten-free version, don’t worry—it’s super easy to do! Here’s what you can swap:

• Use oats labeled gluten-free since regular oats might have traces of gluten.
• Swap out the all-purpose flour for almond flour, oat flour, or a 1:1 gluten-free baking blend.
• If your mixture feels too crumbly, add a binder—mix 1 tablespoon of flaxseed meal with 3 tablespoons of water, let it sit for a few minutes to form a gel, then stir it in to help hold everything together.

How to Store Oatmeal Bars So They Stay Fresh & Tasty

Once your bars have cooled, here’s how to keep them fresh and ready whenever you need a quick snack.

• Room Temp: Up to 3 days in an airtight container—perfect if you’re eating them quickly.
• Fridge: Up to a week—they stay firm and chewy! Just let them come to room temp before eating.
• Freezer: Up to 3 months—wrap them individually for an easy grab-and-go snack.
